steps:a) select substrate with placeholders, b) dispose and align substrate on substrate holder in chamber, c) select transfer layer with openings, d) dispose and align transfer layer over substrate with openings aligned to placeholders, e) add liquid above transfer layer, raising transfer layer on liquid column, f) introduce graphene pieces onto liquid film in openings, g) reduce distance between substrate and graphene pieces until graphene disposed on placeholders
description:Inventive method: substrate with placeholders aligned on substrate holder in chamber; transfer layer with openings aligned over substrate; liquid added to chamber raising transfer layer; graphene pieces introduced onto liquid film in openings; distance between substrate and graphene reduced until graphene disposed on placeholders. Liquid may be removed to lower transfer layer, or substrate lifted via slow lifting mechanism.
